To all who/m, 'it may concern.'

Be it known that I, Ma'r'rr PirrrinltrNnN, manufacturer, subject oit the Grand Duchy ot Finland, residing at No. Holmniisgatan, in the city oit Helsingfors, Finland, fltussia, have invented certain new and usevtul Improvements in Hammocks, ot which the 'following is a specification.

This invention relates to hammocks, and has for its object to provide a hammock which can be easily attached and regulated as to its length and depth without the necessity oit untastening the hammock.

The hammocks at present in use are provided at one end or both ends `with crosspieces Vinteinletl to keep the hammock cxtended, and in order to also keep the middle portion oit the hammock extended, separate marginal cords are provided which run along the outer edges of the hammock from end to end, and separate ropes are used t'or attaching the hammock. The special 0bject oi the rin is to hold the main parts of the hammock together. The principal drawback ot' such a hammock lies in the tact that the outer 'meshes of the net which pass through the holes in the cross-pieces are specially subject to rapid wear, as they are always rubbing at the same places against the sharp edges ot the said holes. Moreover, the hammock itself is more extensible than the said marginal cords, so that it becomes impossible to adjust the length oit the hammock, as the marginal cords are connected to the rings. Consequently, when the hammock is in use, the entire weight ot the person in the hammock rests on a few cords in the middle of the hammock, whereby said cords are still more stretched besides having' to support a vgreat load.

The hammock, made in accordance with my invent-ion, can be readily adjusted to the desired length, and also the depth ot' the hammock can be regulated at will without that the hammock need be unt'astened. This object is attained by so assembling the main parts of the hammock that those parts which are most subject to wear do not always occupy the same position relative to each other, so that the ent-ire hammock will be subjected to more 0r less uniitorm wear.

In the drawing Figure l is a side view of one form o't my new hammock with the crosspieces set far apart, Fig. 2 is a similar view showing the cross-pieces nearer together. Fig. 3 is a plan view of one end ot the hammock, Fig. t a section through one oic the tension pieces.

The hammock consists ot. the net g, in place o'l which, it desired, a cloth can be used, the cross-pieces j and the tension pieces 7L, the cross-pieces being intended to keep the hammock extended and to so support the same that the tension is distributed over the entire, cross-piece. '.l he cross pieces by means ot. the apertures fr allow ttor the adjustment o'tl the length and depth oit the hammock.

Ihe tension pieces L are intended to connect the suspension and the tension ropes in such a manner that these ropes may be joined to 't'orm a single rope, c, 7), c, d, c, which, as shown in the drawing, takes the :following course.: First it is drawn through the openings 2f in one ot the tension pieces it, then through some oit the holes /r in the corresponding cross-piece f, then through the hole Z in the projection oi the, tension-piece 7l., and then through the outside holes r o'i the said cross-piece to the other ci, ;ssj')iere, ctc., thus extending around the entire hammock, torming the marginal cords and the tension cords c, and (l, and the suspension cord (t. ABy means ot this arrangement one can adjust the cross-pieces j and the tension-pieces t to regulate both the length and depth of the hannnock by increasing or de,- ereasing the distance between the two crosspieces on one side, and between the places ot attachment and the tensitm-pieces on the other side. By the arrangement as described, the suspension-cord can also be increased or decreased eitherl over its entire length or at one side of the hammock only.

I claim as my invention:

A, hammock comprising in combination with a net and two cross-pieces adapted to hold the ends of the net extended and proment of the said cr0ss-pieces and tension- 10 vided with apertures, two tension-pieces, one pieces.
